Personally, my resistance to change isn't really always surrounding plans, however, when I do plan, I usually have it in my head that "this is what's going to happen" and when it doesn't I try very hard to not show my discomfort. It actually does make me pretty upset. Not meltdown upset, but extremely annoyed and I want to not speak to anybody for a bit until I can either finish the plan, solve the problem, or just wait until my emotions pass when I feel better. I know I have poor planning skills, so I may make a plan and have a hard time with following through with it, or I get overwhelmed by my own plans even if it's small and I end up not doing anything at all. It's a horrible cycle. Yet, when someone changes their plans and their mind about things I get upset.
I think one of the biggest ways my resistance to change manifests is through being told to do something differently when I feel my way is the way I'm used to. An example being, someone telling me to get new shoes and taking me shoe shopping even though I don't see the point and I dislike the feeling of new shoes for a while. I am only comfortable with change when I am initiating it myself and not forced into it by someone else. As a kid, I remember hating shoe shopping and shopping in general because it felt like a waste of time when I was happy with what I already had. I'd get very upset and be stubborn about it. In summer, I wore a coat because I hated the change in wardrobe once the seasons changed. It's like I have an idea, want to stick with that idea, and when someone else says "No, do it this way. It's better." I get upset because it's new and I don't like that "new". I'd prefer to do it how I've always done it instead of trying new ways. Not necessarily because it's "easier" or "better".
